Specialty Expressions: aurora
| Expressions | Domain | Definition | |
| Aurora (plural: aurorae) | Aerospace | The light radiated by ions and atoms in Earth's upper atmosphere, in the region of the Earth's poles. Those that occur during magnetic storms can create extremely impressive spectacles. The Aurora australis, or "Southern Lights" occur near the South Pole while the Aurora borealis, or "Northern Lights" occur near the North Pole. (references) | |
| Aurora (short for polar aurora) | Aerospace | A glow in the sky, often observed in a ring-shaped region around the magnetic poles ("auroral zone") and occasionally further equatorward. The name comes from an older one, "aurora borealis," Latin for "northern dawn," given because an aurora near the northern horizon (its usual location when seen in most of Europe) looks like the glow of the sky preceding sunrise. Also known as "northern lights," although it occurs both north and south of the equator. The aurora is generally caused by fast electrons from space, guided earthward by magnetic field lines, and its light comes from collisions between such electrons and the atoms of the upper atmosphere, typically 100 km (60 miles) above ground.
